This application claims priority to a Chinese patent application No.201710153127.0 filed on Mar. 15, 2017, disclosure of which isincorporated herein by reference in its entirely.

TECHNICAL FIELD

The present disclosure relates to the display field, and particularly toa display panel and a display device.

BACKGROUND

Currently, commonly known flat panel displays (FPDs) include LiquidCrystal Display (LCD) panels and Organic Light Emitting Diode (OLED)display panels, both types of which have array substrates for drivingpixel units to emit light. Array substrates are provided with aplurality of gate lines for supplying scanning signals, a plurality ofdata lines perpendicular to the plurality of gate lines for supplyingdata signals, and a plurality of pixel units arranged in areas definedby the plurality of gate lines and the plurality of data linesintersecting each other, where each of the plurality of pixel units isprovided with a Thin Film Transistor (TFT) and a pixel electrode, wherea gate electrode, a source electrode and a drain electrode of the TFTare respectively connected to one of the plurality of gate lines, one ofthe plurality data lines and the pixel electrode.

When a display panel is running, the plurality of gate lines arecontrolled by gate drivers and the plurality of data lines arecontrolled by source drivers, where the gate lines are turned on row byrow under control of gate drive signals generated by the gate drivers,and data voltages of the corresponding rows generated by the sourcedrives are sent to the corresponding pixel electrodes through data linesto charge the pixel electrodes, so that gray-scale voltages required fordisplaying each gray-scale are formed in the pixel electrodes and theneach frame of image is displayed. Conventionally, most gate drivers areshifted in a single direction, that is, once a circuit starts running,the gate driver is usually shifted from the first gate line to the lastgate line, each of the plurality of data lines intersects with theplurality of gate lines from the first row to the last row, and pixelunits connected to different data lines are usually in same quantity andcolors.

Conventionally, when the display panel is applied in virtual reality oraugmented reality, the viewable area for the left eye and that for theright eye are usually different. To enhance visual effects, the refreshrate of the display panel usually needs to be improved to 120 Hz. Afterthe improvement of the refresh rate, the charging period of the displaypanel is apparently squeezed, resulting in poor display quality, andespecially as the display panel resolution is getting higher, thecharging period becomes crucial to improvement of the display effect.

DETAILED DESCRIPTION

The disclosure will be further described below with references to theaccompanying drawings and embodiments. It should be noted that thefollowing embodiments described herein are merely for explaining thepresent disclosure rather than limiting the present disclosure.Additionally, merely partial contents associated with the presentdisclosure rather than all contents are illustrated in the accompanyingdrawings for ease of description, and a same reference sign is used indifferent drawings.

FIG. 1 is a schematic diagram showing a display panel according to anembodiment of the present invention. As shown in FIG. 1, the displaypanel includes a plurality of gate lines (SLs) extending in a rowdirection and arranged in a column direction, a plurality of data lines(DLs) extending in a column direction and arranged in a row direction, aplurality of pixel units arranged in an array of M rows by N columnsdefined by the plurality of gate lines and the plurality of data linesintersecting each other, a first gate driver 101 connected to pixelunits from the first row to the mth row; and a second gate driver 102connected to pixel units from the (m+1)th row to the Mth row.

Pixel units from the first row to the mth row of the nth column areconnected to an integrated circuit through one of the plurality of datalines, and pixel units from the (m+1)th row to the Mth row of the nthcolumn are connected to the integrated circuit through another one ofthe plurality of data lines, where M, N, m and n are positive integerssatisfying the following conditions: 1<m<M and 1<n<N.

The display panel of this embodiment can be either an LCD panel or anOLED panel, which is usually provided with an array substrate. The arraysubstrate includes the plurality of pixel units with TFTs, where a TFTis electrically connected to one of the plurality of gate lines and oneof the plurality of data lines and thereby electrically connected to agate driver and a source driver. The gate driver electrically connectedto gate electrodes of the TFTs functions as a switch for turning on andoff one or more TFTs. When the gate electrode of one TFT is turned on,data signals generated by the source driver are sent to the pixel unitcorresponding to the TFT through one data line.

Usually each of the plurality of gate lines (SLs) extends in the rowdirection (first direction in FIG. 1) and is arranged in the columndirection (second direction in FIG. 1). Each of the plurality of datalines extends in the column direction and is arranged in the rowdirection. The plurality of pixel units are arranged in an array of Mrows by N columns defined by the plurality of gate lines and theplurality of data lines intersecting each other. That is, the displaypanel includes M rows of pixel units, which are numbered 1, 2, . . . ,m, m+1, . . . , M in turn, where m and M are positive integers thatconform to formula 1<m<M; and the pixel units are further arranged in Ncolumns, which are numbered 1, 2, . . . , n, . . . , N in turn, where nand N are positive integers that conform to formula 1<n<N.

As shown in FIG. 1, each of the plurality of pixel units in the array ismarked with coordinates. For example, the pixel unit in the first row ofthe first column (m=1, n=1) is marked with (1, 1) in FIG. 1. Similarly,the pixel unit with coordinates (2, N) is located in the second row ofthe Nth column.

The plurality of gate lines and the plurality of data lines are markedin a similar way. Each of the plurality of data lines extends in thecolumn direction (second direction in FIG. 1) and are arranged in thefirst direction shown in FIG. 1, and therefore the plurality of datalines extending along the first direction are marked with DL 1, DL 2, .. . , and so on. The plurality of gate lines extending along the seconddirection are marked with SL 1, SL 2, . . . , and so on.

The display panel according to this embodiment of the present disclosurefurther includes the first gate driver 101 connected to pixel units fromthe first row to the mth row and the second gate driver 102 connected topixel units from the (m+1)th row to the Mth row.

Pixel units from the first row to the mth row of the nth column areconnected to the integrated circuit through one of the plurality of datalines and pixel units from the (m+1)th row to the Mth row of the nthcolumn are connected to the integrated circuit through another one ofthe plurality of data lines.

The First gate driver 101 and the second gate driver 102, which operateindependently of each other, receive different start signals from theintegrated circuit and thereby are independently driven. Among the pixelunits in a same column, at least one of the pixel units (PXs) that aredriven by the first gate driver 101 and other ones of the pixel units(PXs) that are driven by the second gate driver 102 are electricallyconnected to different data lines. As shown in FIG. 1, among pixel unitsin the second column, namely the pixel units with coordinates (1, 2),(2, 2), (M−1, 2) and (M, 2), pixel units with coordinates (1, 2) and (2,2) electrically connected to the first gate driver 101 are connected tothe data line (DL) 2 while pixel units with coordinates (M−1, 2) and (M,2) electrically connected to the second gate driver 102 are connected tothe data line (DL) 3. In this way, pixel units of the display panel aredivided into two parts, which do not affect each other and are turned onseparately and supplied with data signals separately.

It should be noted that although the display panel is divided into twoparts, the display panel as a whole displays a complete image. Thedisplay panel according to this embodiment has a plurality of drivemodes, which are given below.

1. The first gate driver 101 and the second gate driver 102 alternatelyrefresh and drive the corresponding pixel units, that is, the first gatedriver receives a first start signal and sequentially supplies gatedrive signals to pixel units electrically connected to the first gatedriver, and then the corresponding pixel units are turned on, receivedata signals and then display images. When the first gate drivercompletes the refreshment, the second gate driver receives a secondstart signal and sequentially supplies gate drive signals to pixel unitselectrically connected to the second gate driver, and then thecorresponding pixel units are turned on, receive data signals and thendisplay images. This drive mode has the same refresh rate as that of therelated art, which is typically 60 Hz, but can reduce power consumptionof the display panel due to the alternate refreshment, so that thisdrive mode is usually applicable to display of static pictures notrequiring high refresh rates.

2. The first gate driver 101 and the second gate driver 102 drive thecorresponding pixel units simultaneously. The first gate driver 101 andthe second gate driver 102 separately receive start signalssimultaneously, and then the two parts of pixel units sequentiallyreceive gate drive signals simultaneously and receive data signals fromdifferent data lines. When the two parts of pixel units equal in thenumber of rows, the scanning frequency of the display panel doubles to120 Hz. Of course, this embodiment does not require that the two partsof pixel units equal in the number of rows. When the two parts of pixelunits do not equal in the number of rows, the scanning frequency of thedisplay panel depends on the refresh rate of the gate driverelectrically connected to more rows of pixel units, in which case therefresh rate of the display panel still increases to a number greaterthan 60 Hz of the related art, thereby achieving better dynamic display.

3. The display panel is in half-screen display mode. Since the firstgate driver and the second gate driver are driven separately, in somespecial display cases, for example, when the display panel is used in acell phone where the display panel needs to display only time ornotification bar at some points, only one of the gate drivers, that is,one of the first gate driver and the second gate driver, needs tooperate, with the other one stopping scanning. Whereas, in the relatedart, such display mode can be achieved only when full-screen scanning isperformed and the part not to be displayed in the display panel issupplied with black screen data signals. Compared with the work mode ofthe related art, the technical solution of this embodiment greatlyreduces power consumption of the display panel and improves the refreshrate.

Optionally, in this embodiment, as shown in FIG. 1, there are (N+1) datalines sequentially extending along the first direction. Each of datalines 2 to N is electrically connected to pixel units (PXs) in twocolumns adjacent to the each of the data lines 2 to N. Among a row ofpixel units, two pixel units electrically connected to a same data lineare connected to different gate lines. As shown in FIG. 1, the data line#2 is electrically connected to pixel units (1, 1), (2, 1), (1, 2) and(2, 2), where the data line #2 is electrically connected to adjacentfirst column of pixel units, to which pixel units (1, 1) and (2, 1)belong, and to adjacent second column of pixel units, to which pixelunits (1, 2) and (2, 2) belong. Additionally, pixel units, which are ina same row and electrically connected to a same data line, are connectedto different gate lines, that is, pixel units (1, 1) and (1, 2), whichare in the same row, are electrically connected to data line #1 and dataline #2 respectively.

Optionally, odd-numbered data lines are electrically connected to pixelunits from the first row to the mth row and even-numbered data lines areelectrically connected to pixel units from the (m+1)th row to the Mthrow; or even-numbered data lines are electrically connected to pixelunits from the first row to the mth row and odd-numbered data lines areelectrically connected to pixel units from the (m+1)th row to the Mthrow.

As shown in FIG. 1, when the number of the plurality of data lines (DLs)is (N+1) and the number of columns of pixel units is N, any column ofpixel units can be adjacent to two data lines, that is, the data linesare located along two sides of each column of pixel units and each ofthe data lines is located between two adjacent columns of pixel units.Each of data line #1 and data line (N+1) is electrically connected toonly one column of pixel units, that is, data line #1 is electricallyconnected to the first column of pixel units, data line (N+1) iselectrically connected to the Nth column of pixel units. Each of thedata lines 2 to N is electrically connected to two columns of pixelunits adjacent to each of the data lines 2 to N. In this case, to makesure that among each column of pixel units, pixel units electricallyconnected to the first gate driver and pixel units electricallyconnected to the second gate driver are connected to different datalines, the odd-numbered data lines can be electrically connected topixel units from the first row to the mth row, that is, pixel unitselectrically connected to the first gate driver are electricallyconnected to the odd-numbered data lines, that is, pixel units from thefirst row to the mth row are electrically connected to only theodd-numbered data lines such as data line #1, data line #3, data line#5, . . . , and so on, and similarly, pixel units from the (m+1)th rowto the Mth row are electrically connected to only the even-numbered datalines such as data line #2, data line #4, data line #6, . . . , and soon.

Therefore, it is impossible that two pixel units connected to a samegate line are connected to a same data line and two pixel unitsconnected to a same data line are connected to a same gate line. Themode of using a data line to connect two columns of pixel units adjacentto this data line makes the number of data lines used to realizesplit-screen display as less as possible, thus reducing difficulty indesign of integrated circuits and complexity in operation of the displaypanel. According to this embodiment of the present invention, eachcolumn of pixel units is divided into two parts, which are electricallyconnected to different data lines respectively, and each of the datalines 2 to N is electrically connected to two columns of pixel unitsadjacent to the data line, so that split-screen display is possible withno extra data lines added.

It should be noted that the quantity of the plurality of gate lines arenot limited in the above embodiment and just need to meet therequirements that two of pixel units, arranged in a same row andelectrically connected to a same data line, are electrically connectedto different gate lines, while among pixel units in the same row, pixelunits electrically connected to different data lines can be electricallyconnected to either a same gate line or different gate lines.

Optionally, a total number of gate lines is 2M, pixel units from thefirst row to the mth row are connected to the first gate driver throughthe first to a 2mth gate lines, and pixel units from the (m+1)th row tothe Mth row are connected to the second gate driver through the (2m+1)thto 2Mth gate lines; and among pixel units in a same row, at least one ofthe pixel units is electrically connected to one of the gate lines andother ones of the pixel units are electrically connected to another oneof the gate lines.

FIG. 1 shows the display panel with a total number of 2M gate lines,that is, the gate lines are twice of the number of the pixel units.Since each of the data lines 2 to N is electrically connected to twocolumns of pixel units adjacent to the each of the data lines 2 to N, toensure that two pixel units in a same row and electrically connected toa same data line are electrically connected to different gate lines, itis necessary to add more gate lines so that data signals of each pixelunit are supplied separately. Moreover, pixel units in a same row andelectrically connected to different data lines can be electricallyconnected to a same gate line, by which the gate lines are actuallytwice the number of rows of the pixel units, thus realizing split-screendisplay with fewest possible flat cables. In this embodiment, doubledgate lines will not affect flat cables of the display panel. Optionally,two of the gate lines are arranged between two adjacent rows of pixelunits, and two of the gate lines electrically connected to a same row ofpixel units are located along two sides of the same row of pixel unitsrespectively.

Taking alternately refreshing and driving the pixel units by first gatedriver 101 and second gate driver 102 as an example, the drive processof the display panel according to this embodiment is as follows: thefirst gate driver 101 receives a start signal and sequentially turns onpixel units from the first row to the mth row through gate lines 1 to2m, and data signals are supplied to two pixel units in a same row andelectrically connected to a data line through the data line, where thedata line is one of the odd-numbered data lines, such as data line #1,data line #3, . . . , and so on. Since the two pixel units in a same roware turned on and off under control of different gate lines, each of thetwo pixel units is driven separately, making upper-half-screen displaypossible. When the first gate driver 101 completes the refreshment, thesecond gate driver 102 receives a start signal and sequentially turns onpixel units from the (m+1) row to the Mth row through gate lines (2m+1)to M, and then data signals are supplied to pixel units through each ofthe even-numbered data lines, such as data line #2, data line #4, . . ., and so on, making lower-half-screen display possible. When the firstgate driver and the second gate driver drive the pixel unitssimultaneously, the two parts of pixel units are turned onsimultaneously, and data signals are supplied to pixel unitselectrically connected to the first gate driver through the odd-numbereddata lines, while data signals are supplied to pixel units electricallyconnected to the second gate driver through the even-numbered datalines, so as to double the refresh rate of the display panel as a whole.

In this embodiment, the pixel units can be electrically connected to thegate lines in multiple ways. As shown in FIG. 1, among pixel units in asame row, pixel units in the odd-numbered columns and pixel units in theeven-numbered columns are electrically connected to different gatelines, for example, among pixel units (1, 1), (1, 2), (1, 3) and (1, 4)in the first row, pixel units (1, 1) and (1, 3) in the odd-numberedcolumn are electrically connected to data line #1, while pixel units (1,2) and (1, 4) in the ever-numbered column are electrically connected todata line #2.

The pixel units can also be electrically connected to the gate lines inother ways. Specifically, FIG. 2 is a schematic diagram showing adisplay panel according to another embodiment of the invention. As shownin FIG. 2, among pixel units (1, 1), (1, 2), (1, 3) and (1, 4) in thefirst row, pixel units (1, 1) and (1, 2) are electrically connected todata line #1 while pixel units (1, 3) and (1, 4) are electricallyconnected to data line #2, where pixel units (1, 2) and (1, 3) areelectrically connected to the same data line. In this embodiment, amongpixel units in a same row, every two pixel units adjacent to each otherare connected to a same gate line and are called a pixel unit group,where every two pixel unit groups adjacent to each other are connectedto different gate lines while every two pixel unit groups, between whichthere is one pixel unit group, are connected to a same data line. Thisconnection mode is different from the connection mode where odd-numberedcolumns of pixel units and even-numbered columns of pixel units areelectrically connected to different gate lines respectively.

FIG. 3 is a schematic diagram showing a display panel according toanother embodiment of the invention. As shown in FIG. 3, the number ofthe gate lines is M and the number of the data lines is 2N, that is, thenumber of the gate lines equals the number of rows of the pixel unitswhile the number of data lines is twice of the number of the columns ofthe pixel units, where each row of pixel units is electrically connectedto one of the gate lines and split-screen display is achieved with datalines added while with no gate lines added. As shown in FIG. 3, thepixel units from the first row to the mth row are connected to the firstgate driver 101 through data line #1 to gate line m respectively whilethe pixel units from the (m+1)th row to the Mth row are connected to thesecond gate driver 102 through gate line (m+1) to gate line Mrespectively. Each data line (DL is electrically connected to only onecolumn of pixel units.

Optionally, odd-numbered data lines are electrically connected to pixelunits from the first row to the mth row and even-numbered data lines areelectrically connected to pixel units from the (m+1)th row to the Mthrow; or even-numbered data lines are electrically connected to pixelunits from the first row to the mth row and odd-numbered data lines areelectrically connected to pixel units from the (m+1)th row to the Mthrow.

Taking alternately refreshing and driving the pixel units by the firstgate driver 101 and the second gate driver 102 as an example, the driveprocess of the display panel according to this embodiment is as follows:the first gate driver 101 receives a start signal and sequentially turnson pixel units from the first row to the mth row through gate lines 1 tom, and then each of the odd-numbered data lines such as data line #1,data line #3, . . . sequentially supplies data signals to two pixelunits in a same row and electrically connected to this data line, makingupper-half-screen display possible. When the first gate driver 101completes the refreshment, the second gate driver 102 receives a startsignal and sequentially turns on pixel units from the (m+1) row to theMth row through gate lines (m+1) to M, and then each of theeven-numbered data lines such as data line #2, data line #4, . . .sequentially supplies data signals, making lower-half-screen displaypossible. When the first gate driver and the second gate driver drivethe pixel units simultaneously, the two parts of pixel units are turnedon simultaneously, and the odd-numbered data lines supply data signalsto pixel units electrically connected to the first gate driver while theeven-numbered data lines supply data signals to pixel units electricallyconnected to the second gate driver, doubling the refresh rate of thedisplay panel as a whole.

Optionally, when M, which is the number of rows of the pixel units, isan odd number, the formula m=(M±1)/2 applies. When M, which is thenumber of rows of the pixel units, is an even number, the formula m=M/2applies, in which case, the display panel as a whole can be divided intotwo parts with approximately the same number of pixel units, that is,the display panel as a whole can be divided into two split screens inthe same size or in the approximate same size, which are drivenseparately and display an image separately. The ways the pixel units aredivided are not limited to those listed in this embodiment. It is alsofeasible to electrically connect pixel units from the first row to the⅓Mth row to the first gate driver and electrically connect pixel unitsfrom the (⅓M+1)th row to the Mth row to the second gate driver. Theactual division mode depends on product requirements.

According to another embodiment of the present invention, a displaydevice is provided, and a schematic diagram of the display device isshown in FIG. 4. As shown in FIG. 4, the display device, which includesany one of the display panels described in the aforementionedembodiments, may be a cellphone, desktop, notebook, tablet or electronicalbum. The display device according to this embodiment includes any oneof the display panels described in the aforementioned embodiments, andtherefore has the advantages of that included display panel.

For the display device and the display panel according to the presentdisclosure, pixel units of the display panel are divided into two partsthat are driven by different gate drivers respectively, and pixel unitslocated in a same column and electrically connected to different gatedrivers are electrically connected to different data lines respectively,by which two parts of the pixel units can be driven and displayedseparately and split-screen display can be performed.

The two parts of pixel units are driven by different gate driversseparately and therefore at least three drive modes are given below: thefirst gate driver and the second gate driver alternately refresh anddrive the pixel units, which is usually applicable to display of staticpictures not requiring high refresh rates since power consumption of thedisplay panel is reduced in this mode; the first gate driver and thesecond gate driver drive the pixel units simultaneously, which isparticularly applicable to virtual reality and augmented reality sincethe refresh rate of the display panel as a whole doubles and hysteresislike trailing will not exist in dynamic display in this mode; and thedisplay panel is in half-screen display mode, where compared with thework mode of the related art by which the part not to be displayed issupplied with black screen data signals, the technical solution of thehalf-screen display mode greatly reduces overall power consumption ofthe display panel and improves the refresh rate.
